The equilateral's lengths are all the same

Also if AB = AD = BD = CD that would mean all those sides have the exact same length

Answers and Explanations

15A. BCD has 2 acute angles and one obtuse angle, so this is an Obtuse Triangle

15B. If beforementioned = 5 cm

Then the perimeter is 5cm x 3 = 15cm

15C. ABC is a Right Triangle

16. abcdef. Measure the angles using a protractor

Answer:

Step-by-step explanation:

The volume (V) of a cone is calculated as

V = $\frac{1}{3}$ area of base × height

= $\frac{1}{3}$ × πr² × height

Here diameter = 22, thus r = 11 and h = 22

V = $\frac{1}{3}$ × π × 11² × 22

= $\frac{1}{3}$ × π × 121 × 22

= $\frac{\pi (121)(22)}{3}$

≈ 2787.64 → C

What is (x+3) (x-7)?

Mariana [72]

Answer:

We can use FOIL to solve this:

F - First

O - Outer

I - Inner

L - Last

$= (x \times x)+(x \times - 7)+(3 \times x)+(3 \times - 7)$

$= {x}^{2} + - 7x + 3x - 21$

$= {x}^{2} - 4x - 21$

Two numbers add to 218. The first is 47 less than the second. What are the numbers

Firlakuza [10]

Defining variables
let n1 be the first number
n2 be the 2nd number

add them together, you get 218
n1+n2 =218

n1 is 47 less than n2
n1=n2-47

do some substitution
n2-47 +n2 = 218

solve for n2

then use n2 to figure out n1
